y[Fo `all 'whomttmay concern:

l Be itoknowngthat I, SAMUEL HUGHES, of Charleston, in, the countyofl Charleston and `Statefof Southl Carolina, have invented certain new andl useful,l Improvements Yin Rice` Pounders;andl doy hereby declare the followingto be afull, clear, and exact description of .the invention, .such eas. will enable others skilledin the art to which itperta'ins to make and use it, referenceubeing had` totheaccoml panyingfdrawings, which lform lfpartof this specication.

My'invention relates to an improvementf in' rice-pounders. d

r In the oldstyle of rice-pounders thepestle was raisedby revolvingarms passingin their revolution through aslot in the pestle-body and `engaging the ,latter atl the" top of the slot.

. y ,gQyying to the undue wearand friction -of the "ffwzo `liftingde vices,and alsoto the great noise produced in the operation of such`machines,they

metwith disfavor andare objectionable inuse.

-- Again, rice-poundershave been made-'wherein lthe pestle is liftedby cams oreccentrics engaging with theopposite sides of "a lifting board or rod attached to the pestle.-7 This lat-l ter form of machine has been found objection- `able inuse, owing .to the-fact'that the cams or eccentrics soon wear away thelifting rod or such parts of the machine, and further compli-` `board, thereby necessitating Vthe. renewal of l catedmechanism is required to maintain the A* proper adjustment of the cams or eccentrics,

' thereby enhancing the cost o'f the machine. .and increasing its liability to become impaired and=nntted for use.

v The object of my invention is to obviate the defects and objectionable features referred to,

Land provide a rice-pounder which shall be simple and economical in its' construction,

durable in use, and Aadapted to be operated at a minimum expenditure of power. I

With these ends in view my invention consists, essentially, in the combination, with a pestle having rollers jourl'ialed-inits body portion, of an oscillating arm the free end of which engages with said rollers, and a cam arranged to engage with a roller journaled in the vibrating arm and lift the same.

My invention further consists in certain ypulley d, attached tothe driving-shaft e. cam, I, is attached to the counter-shaft G, or

other details of construction and combinations of parts, as willfhereinafter be described, and pointed out in the claims.

In the 'accompanying drawings, Figurel is a View, in side elevation, of my improved ricepounder. Fig. 2 is a front elevation of the same.- Fig. 3 is a detached view, in -vertical section, of the pestle. Fig. 4 is a longitudinal section of one lof the rubber-cushioned rollers. Fig. 5 is a transverse section of the roller. Fig. 6 is a side elevation, and Fig. 7 an end elevation, of the roller. Fig. 8 is a detached view ofV the pestle-cap, bolt, and nut. Fig. 9 is a plan view of the nut. Fig. 10'is a transverse section of the upper portion of the peslale-body. Figs. 1l and 12 are modifications.

.are the upright frame-pieces, secured attheir flower ends to sills C, and at their upper ends to the upper pestle-gnide, D.

Pestle E is retained in place by the upper and lower guides, D F, said guides having openings formed therein to allow ot' thefree Ireciprocation of the pestle, and to prevent any lateral displacement of the same.

G is a countereshaft, supported in bearings a, mounted on beams b, secured at one end to the pounder-frame, and at their opposite' ends to the frame-worl'r' E, located in rear of the mortar. f

H is a band-pulley, secured to counter-shaft G, and driven by a belt, c, `which passes. over A it may be bolted to or cast solid with the pulley H. A vibrating arm, J, is hinged at f to the frame-work H.

To the under sideof the vibrating arm is secured a bracket, K, in which is journaled a roller, L, Awhich lengages with the cam I, the

latter serving tolift the arm at each-revolution of the counter-shaft and allow it to fall, by its gravity, when the outer end of the cam is released from contact with the roller.

The outer or free end of the arm J is inserted between rollers la k journaled in the body L of the pestle. As the cam I is revolved it engages with the roller L and lifts the vibrating arm at each revolution of the cam. The roller IOC) L rolls over the periphery of the cam, and thus the friction and wear are vervslight between such parts. As the vibrating arm is raised its outer or free end engages with the rollers in the body of the pestle and raises the latter. The vibrating arm will, of course, describe an are of a circle when raised by the cam, and hence its free end will have an endwise movement between the rollers; but the friction and wear are reduced to a minimum by the employment of the rollers, which engage the upper and lower sides of the arm.

Rollers k k'and L are preferably constructed in the manner illustrated in Figs. 4, 5, 6, and 7. Each roller is composed of the hub Q, provided with a llange, q', at one end, and with removable tlange, q2, at the opposite end, the flange q2 heilig retained in place by means of screws g3 or other suitable devices. The hub Q is mounted on a shaft, Q2, having journals q4 on opposite ends thereof.

Within the annular groove lt formed between the flanges q q2 is placed a rubbertire or ring, R', which serves asa cushion to relieve the machine of any sudden shocks, and also deadens the noise of the machine. Instead of using rubber-cushioned rollers the latter may be made solid with unyielding peripheries, and the free end of the vibrating lever be provided with cushions, as shown in Fig. ll.

S S' represent rubber cushions, which are secured to the upper and lower edges or sides of the vibrating lever by tacks or screws s. A strip of leather, S2, is then passed around the end of the lever and over the rubber cushions, the leather strip being secured in place by screws s,inserted through plates s2, having countersunk holes s for the reception of the screw-heads.

The pestle is made with a hollow iron body, L', which may be ot' any desired length, size, and form-that is, it may be square, round, diamond-shaped, or other form in cross-section.

To the lower portion of the pestle is secured the cap m, by means of the bolt N. The head n of the bolt is inserted in a recess, n', in the i'aceofthe cap, while the screw-threaded shank engages the nut N', the latter being elongated in form and adapted to be inserted through the opening in the lower end of the pestle.

The cap m may be made of any desired form and size, and when unduly worn can be readily removed and replaced by a new one.

Within the hollow body ot' the pestle are placed iron borings 0, for the purpose of increasing the weight of the pestle. and b v varying the quantity of iron borings the pestle may be made of any desired weight.

Instead of employing iron borings, I may use sand, or any material found suitable for the purpose, the object being to readily ad just the weight of the pestle. This form of pestle is also adapted for use with other styles ot' rice-pounders, and may be constructed as illustrated in Fig. 12, wherein P represents a lifting-board, secured to the upper end of the hollow pestle by bolts p.

Hence I would have it understood thatI do not restrict myself to the employment of this improved pestle is the particular construction of pounder herein shown and described.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a rice-pounder, the combination, with a pestle and rollers journaled in its body portion, of a vibrating arm having its free end inserted between said rollers, the peripheries of the latter being arranged and adapted to engage with the upper and lower edges of the vibrating arm, substantially as set forth.

2. In a rice-pounder, the combination, with a pestle and rollers journaled in its body portion, of a vibrating arm having its free end inserted between said rollers, and a rubber cushion interposed between the rollers and vibrating arm, substantially as set forth.

3. In a rice-pounder, the combination, with a pestle having rollers journaled in its body portion, said rollers having rubber.tires attached thereto, of a vibrating arm or lever having its free end inserted between said rollers, the latter arranged and adapted to travel backward and forward on the upper and lower edges of said vibrating arm, substantially as set forth.

4. A pestle constructed with a hollow body and adjustably weighted by material placed within the chamber of the pestle, substantially as set forth.

5. A pestle constructed with a hollow body and provided with a removable cap, and adjustably weighted by material placed within the chamber of the pestle, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 4th day of August, 1880.
